 Hardware Installation 

PS/2 Mouse and PS/2 Key board Ports 

Connect a PS/2 mouse to the green 6-pin mini DIN connector. The 

system will automatically assign IRQ 12 to the PS/2 mouse if one is 

connected. 

Connect a PS/2 keyboard to the purple 6-pin mini DIN connector.   

If you want to connect a standard AT size (large DIN) connector, you 

must use an adapter. 

Universal Serial Bus Ports 

You can connect two USB devices or USB hubs to the USB ports.

The USB ports provide a hardware interface for low-speed 

peripherals such as the keyboard, mouse, joystick, scanner, printer 

and telephony devices, and also support MPEG-1 and MPEG-2 

digital video. The USB ports have a maximum bandwidth of 480 

Mbits/sec (equivalent to 60 Mbytes/sec), and up to 127devices can 

be attached. Fast devices can use the full bandwidth, while 

lower-speed ones can transfer data using a 60 Mbytes/sec 

sub-channel.
